Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of loader equipment, specifically relating to a support and anti-tipping device for the outer casing of a loader. Background Technology
[0002] A scraper is a machine capable of comprehensively performing excavation, soil transportation, unloading, filling, and leveling, and is widely used in the construction of highways, railways, mines, ports, water conservancy projects, and other engineering projects. The outer casing of a scraper is used to load and protect equipment, and its stability after being opened is crucial; instability can lead to damage to the equipment inside. However, existing scraper outer casings have some problems during use. For example, when the scraper is being inspected, repaired, or maintained, the outer casing is prone to tipping over due to a shift in the center of gravity after opening. This not only causes equipment collisions and affects work efficiency but also poses a safety threat to surrounding personnel and equipment. Furthermore, the outer casing bears significant pressure when opened, and the existing support structure cannot provide sufficient support in a confined space, further increasing the risk of tipping.
[0003] Patent CN 217198297 U discloses an automatic tilting and dumping chip cart, including a box and a base frame. The box includes a base plate, a front plate, a rear plate, a left side plate, and a right side plate. The front plate is inclinedly mounted on the base plate. A tilting limiting gear is provided at the bottom of the front plate, and a gear groove that meshes with the tilting limiting gear is provided on the base frame. A limiting shaft is provided on the tilting limiting gear, and a limiting plate is provided on the base frame. The limiting plate has a V-shaped slot, and the limiting shaft is located in the V-shaped slot. A hook limiting body is provided on the rear plate, and a hook assembly is provided on the base frame at a position adapted to the hook limiting body. When dumping chip materials, after the hook assembly separates, the center of gravity shifts forward due to the action of the material, and the cart automatically tilts to complete the dumping of the chip materials. During this dumping process, the cart is limited by the trajectory of the limiting shaft within the limiting plate, so that the cart tilts to the correct position and stops, preventing the cart from tilting excessively and derailing. However, after the cart tilts, the cart is only limited by the limiting plate and the limiting shaft, resulting in an unstable cart support structure that is prone to failure. Therefore, it is necessary to develop a support and anti-tipping device that provides sufficient support for the outer casing of the loader after it is lifted, so as to prevent the outer casing from tipping over due to shift in the center of gravity or excessive pressure.

[0006] Furthermore, the fixing plate is located on the upper part of the hinge pin seat. When the outer casing device is lifted and rotated, the fixing plate engages with the lower part of the hinge pin seat to prevent the outer casing device from tilting backward.
[0007] Furthermore, the hinge pin seat includes a rotating arm and a fixed arm. The rotating arm is fixed to the lower part of the outer casing device, and the fixed arm is fixed to the support plate.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0019] Example 1
[0020] Reference Figure 1-2 A support and anti-tipping device for the outer casing of a loader includes an outer casing 1, a support rod 2, a rotating shaft 3, a support plate 4, a U-shaped block 5, a stop block 6, a hinge pin seat 7, and a fixing plate 8. The top of the support rod 2 is connected to the outer casing 1 via the rotating shaft 3. The U-shaped block 5 is fixed on the support plate 4. The stop block 6 is provided on the rear side of the U-shaped block 5 and is fixed on the support plate 4. The outer casing 1 is mounted on the support plate 4 via the hinge pin seat 7, and the fixing plate 8 is mounted on the hinge pin seat 7.
[0021] The support rod 2 rotates as the outer casing 1 is lifted via the pivot 3. The bottom of the support rod 2 engages in the groove of the U-shaped block 5, limiting its position and thus preventing the outer casing 1 from tipping over. The stop block 6 further limits the support rod 2, preventing it from rotating 360°, thus limiting the outer casing 1 and preventing it from tipping over. The fixing plate 8 limits the rotation angle of the connecting pin seat 7, preventing the outer casing 1 connected to the connecting pin seat 7 from tipping over.
[0022] Furthermore, the fixing plate 8 is disposed on the upper part of the hinge pin seat 7. When the outer casing device 1 is lifted and rotated, the fixing plate 8 is engaged with the lower part of the hinge pin seat 7 to prevent the outer casing device 1 from tilting backward.
[0023] Furthermore, the hinge pin seat 7 includes a rotating arm 9 and a fixed arm 10. The rotating arm 9 is fixed to the lower part of the outer casing device 1, and the fixed arm 10 is fixed to the support plate 4. The rotating arm 9 and the fixed arm 10 are rotatably connected by a pin 11, and a fixing plate 8 is installed on the rotating arm 9. The position of the fixing plate 8 allows for flexible adjustment of the rotation angle of the outer casing device 1 when it is lifted. When the position of the fixing plate 8 moves downward, the rotation angle of the rotating arm 9 is small, and the fixing plate 8 will engage with the fixing arm 10, resulting in a smaller rotation angle when the outer casing device 1 is lifted. When the position of the fixing plate 8 moves upward, the rotation angle of the rotating arm 9 is large, and the fixing plate 8 will engage with the fixing arm 10, resulting in a larger rotation angle when the outer casing device 1 is lifted.
[0024] Furthermore, there are two rotating arms 9, respectively located on both sides of the fixed arm 10. This increases stability, making the limiting position more reliable and stable when the outer casing device 1 is lifted and rotated.
[0025] Furthermore, the rotating shaft 3 is located at the rear of the outer casing device 1.
[0026] Furthermore, the groove of the U-shaped block 5 is located on the rear side of the U-shaped block 5, and the hinge pin seat 7 is connected to the rear end of the outer casing device 1. When the lower part of the support rod 2 is engaged in the groove of the U-shaped block 5, the force exerted on the outer casing device 1 can prevent the outer casing device 1 from rotating forward and tipping over.
[0027] When the support and anti-tipping device of the outer casing of the loader of this utility model is working, when the outer casing 1 is lifted and rotated, the outer casing 1 rotates backward around the pin 11. At the same time, the support rod 2 rotates with the rotating shaft 3. When the fixing plate 8 is engaged with the fixing arm 10 of the hinge pin seat 7, the outer casing 1 stops rotating. The fixing plate 8 limits the outer casing 1 and prevents the outer casing 1 from continuing to rotate backward. At this time, the lower part of the support rod 2 is engaged in the groove of the U-shaped block 5, which limits the outer casing 1 and prevents the outer casing 1 from rotating forward, thus realizing the fixed support of the outer casing 1 and effectively preventing the outer casing 1 from tipping over.
